gcc.target/aarch64/eh_return-3.c fails when running the testsuite with
`-march=armv9-a+sve` . I think it is a good idea to try to keep the
testsuite clean when running with different -march=/-mcpu= options
even. I know there are many failures due to -march=/-mcpu option right
now but this is a new testcase and all.

Thanks,
Andrew
